1. In this vid, you can see all the CAD cautions for the configuration, transfer pumps off and prime pumps on. When the CAD is switched off, you get the CAD DEGR caution and Master Caution.
You have no indication of the transfer or prime pump cautions and also no fuel indication.
2. In this video, you can see the CAD showing all normal, with the transfer pumps off. The CAD is then switched off, and the CAD DEGR caution and master caution illuminate. With the caution acknowledged and CAD off, the Prime pumps are then switched on.
The prime pumps are switched on at 8 seconds and you will notice that there is no prime pump caution, no master caution and with all the fuel pumps in the wrong position there is no indication of anything being wrong.
Perhaps the pilot knew the system well enough, and given a CAD failure knew that the only indication any fuel state they would now be getting would be the '10 minutes to land' LOW FUEL Warning. With no Red warnings so far, getting back to base may have been seen as viable. After all, it is within the departing fuel endurance, there was still more than 10 mins of fuel in the ac, albeit in the wrong tank, and if you're expecting a 10 minute warning that hasn't appeared yet, surely you believe that have enough fuel remaining.
With this in mind, 4 minutes before the engines flamed out, the ac was in contact with ATC which would indicate that at least 6 minutes before this the Red Warnings were on, yet nothing was mentioned
